Chronic migraine with aura, not ntrct, without stat migr

This code describes a type of chronic migraine characterized by recurring headaches accompanied by sensory disturbances (aura), which is not resistant to treatment and does not involve a prolonged, severe migraine attack lasting more than 72 hours. Chronic migraine is defined as headaches occurring 15 or more days per month for over three months, with at least 8 of those days meeting criteria for migraine.

Use this code when documentation clearly indicates a patient experiences chronic migraine with aura, and the physician explicitly states it is "not intractable" and "without status migrainosus." This diagnosis is typically supported by a detailed headache diary or patient history confirming the frequency and characteristics of the headaches and aura.

• Ensure the documentation specifies "with aura" and explicitly rules out both "intractable" and "status migrainosus."
• Distinguish from episodic migraine with aura (G43.10-) and chronic migraine without aura (G43.E01).
• Always review the full diagnostic statement to capture all specific characteristics of the migraine.
